What stood out to me most about Allegro was the high quality of ingredients. On that first bite, you can tell that the olive oil is extra virgin and the parmesan is freshly shaved. Everything they served was imported from someplace legit. It's a nice enough place in terms of ambiance and the edge table where I was seated was excellent for people watching on the casino floor. The service was attentive without being annoying and took special care to remember who I was on subsequent visits. The prices are a little high (but that's the Wynn for ya) and it's not exactly like grandma's kitchen (preventing that elusive 5th star) but as far as Italian restaurants in a desert go, head and shoulders above the crowd. Dine in confidence.
